Ignition switch, 4.0 manifold, clutch and brake servo on the Wrangler TJKnown weak points

Engine / equipment: Jeep Wrangler TJ (2.4 and 4.0)
Period mentioned: 1997–2006
Symptoms: Water and dirt in the ignition switch causing a short and a fire risk (2001–2002); on the 4.0, the manifold design lets debris build up near cylinder 3, with a fire risk (2000–2002); a clutch master-cylinder rod that breaks on the 6-speed gearbox (2006); a split brake-servo vacuum-reservoir diaphragm (1998); a steering-wheel airbag clock spring that breaks at full lock (1997); dashboard earth screws working loose (1999).
Possible cause described: Defects documented by US recalls; European cars may have equivalent campaigns: check by VIN.
Check for the garage: Check campaigns by VIN; keep the 4.0 manifold area clean.

Engines: 2.8 CRD (Diesel)

EGR, turbo and timing belt on the 2.8 CRD (VM Motori)Engine

Engine / equipment: 2.8 CRD by VM Motori: Jeep Cherokee, Wrangler, Chrysler Voyager, Dodge Nitro and Lancia Voyager
Period mentioned: 2001–2018
Symptoms: Hesitation, smoke and loss of power from the EGR or particulate filter; a failing turbo or intercooler; if the timing belt breaks, serious damage (interference engine).
Possible cause described: The block is considered robust: problems usually come from the ancillaries (turbo, intercooler and emissions equipment, especially the EGR valve). Owners point out that the timing belt is expensive and must be changed on time (about 160,000 km).
Check for the garage: Check when the belt was changed; read the EGR and filter codes; check the turbo and intercooler pipes.
